Description

Technical Field

[0001] This utility model relates to the field of metal shell manufacturing technology, specifically to a welding fixture for manufacturing metal shells. Background Technology

[0002] Metal casing manufacturing refers to the process of machining metal materials into thin-walled components using specific techniques, and then welding multiple components together to form a closed or semi-closed casing, primarily used to house, protect, or support internal components. Welding fixtures are specialized jigs used to fix and position metal casing components to ensure welding accuracy and stability.

[0003] Existing welding fixtures mainly include a base, multiple lead screws for horizontal and vertical adjustment, and clamping components. The position of the clamping components is adjustable to firmly clamp the housing parts and prevent them from moving during welding. However, they have the following shortcomings in use:

[0004] 1. During the welding process, high temperatures are easily conducted to the clamping parts, causing thermal expansion and contraction of the clamping parts, resulting in unstable positioning of the shell, displacement, and affecting the welding effect;

[0005] 2. Welding slag is produced during electric welding. The slag may splash into the gaps between various structures of the welding fixture, which is difficult to clean and can cause positioning jamming. Utility Model Content

[0006] I. Technical problems to be solved

[0007] The technical problem to be solved by this utility model is that the clamping parts are prone to thermal expansion and contraction during high welding temperatures, which causes unstable positioning and welding slag to easily enter the tooling gap, causing positioning jamming.

[0008] II. Technical Solution

[0009] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a welding fixture for manufacturing metal shells, including an operating table;

[0010] An inverted L-shaped plate is provided on the rear side above the operating table. The L-shaped plate faces forward and has a corresponding support plate that slides on its upper end. The support plate is inverted U-shaped, with one end located above the middle of the operating table. An arc-shaped baffle is provided above the horizontal side of the L-shaped plate.

[0011] A through groove is provided below the side wall of the two support plates that are close to each other at the front end. A clamping plate is inserted into the through groove and a clamping member is clamped between the clamping plates. The end of the clamping plate away from the clamping member is inclined, and the end closer to the operating table is greater than the height of the through groove, while the other end is less than the height of the through groove.

[0012] The clamping component has a water channel inside, and one end away from the center of the operating table is connected to two circulating water pipes. The other end of the circulating water pipes is connected to a chiller.

[0013] As an improvement, a rectangular groove is provided above the horizontal side of the L-shaped plate, and a bidirectional screw is provided between the left and right inner walls of the rectangular groove. One end of the bidirectional screw extends out of the L-shaped plate and is connected to a motor, and one end of the support plate is inserted into the rectangular groove and threaded onto the outside of the bidirectional screw.

[0014] As an improvement, the baffle is made of transparent PVC material.

[0015] As an improvement, the clamping member includes a horizontal plate located between the clamping plates and inserted into the through slot, and the end of the horizontal plate near the operating table is provided with an arc-shaped plate.

[0016] As an improvement, the number of clamping components is multiple, and the curvature and size of the arc plate are different.

[0017] As an improvement, the side wall of the clamping plate that is in contact with the horizontal plate of the clamping member is provided with anti-slip texture.

[0018] III. Beneficial Effects

[0019] The advantages of this utility model compared with the prior art are as follows:

[0020] 1. This utility model has specially opened water channels inside the clamping component and formed a closed-loop cooling circuit with the chiller through the circulating water pipes connected at both ends. During the welding process, the chiller continuously delivers low-temperature coolant to the water channels of the clamping component, which quickly removes the heat conducted to the clamping component by the high-temperature welding, so that the clamping component is always maintained in a stable temperature range, avoiding dimensional changes or positional shifts due to thermal expansion and contraction, and ensuring firm and stable positioning.

[0021] 2. This utility model uses an arc-shaped transparent PVC baffle set above the horizontal side of the L-shaped plate to directly block the welding slag generated in the welding area, preventing it from splashing into the gaps of the core adjustment structure such as the bidirectional screw and rectangular groove behind it. The clamping part is inserted between the clamping plates and fixed in the through groove, so that after the welding slag enters the gap, the clamping part and clamping plate can be directly disassembled for cleaning. The welding slag is easy to clean and avoids positioning jamming. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] As attached Figure 1-5 As shown, a welding fixture for manufacturing a metal shell includes an operating table 1. An inverted L-shaped plate 2 is provided on the rear side of the operating table 1, facing forward, and a supporting plate 3 is slidably provided on the upper end of the L-shaped plate 2. A rectangular groove 10 is provided on the upper horizontal side of the L-shaped plate 2. A bidirectional screw 11 is provided between the left and right inner walls of the rectangular groove 10. One end of the bidirectional screw 11 extends out of the L-shaped plate 2 and is connected to a motor 12. One end of the supporting plate 3 is inserted into the rectangular groove 10 and threaded onto the outside of the bidirectional screw 11. The motor 12 drives the bidirectional screw 11 to rotate, so that the supporting plate 3 threaded onto the outside of the bidirectional screw 11 is restricted by the rectangular groove 10 and can move synchronously toward the side closer to or away from the center of the operating table 1. The supporting plate 3 is inverted U-shaped, with one end located above the middle of the operating table 1 to cooperate in clamping the metal shell located on the operating table 1.

[0030] The L-shaped plate 2 has an arc-shaped baffle 4 above its horizontal side, which can directly block the welding slag generated in the welding area and prevent it from splashing into the gaps of the core adjustment structure such as the bidirectional screw 11 and the rectangular groove 10 behind it.

[0031] Furthermore, the baffle 4 is made of transparent PVC material, which makes it easy to observe the status of the core adjustment structure such as the bidirectional screw 11 and the rectangular groove 10 above the L-shaped plate 2.

[0032] A through groove 5 is provided below the side wall of the two support plates 3 that are close to each other at the front end. A clamping plate 6 is inserted into the through groove 5 and is positioned opposite each other. A clamping member 7 is clamped between the clamping plates 6. The clamping member 7 includes a horizontal plate located between the clamping plates 6 and inserted into the through groove 5. The horizontal plate has an arc-shaped plate at the end near the operating table 1. The end of the clamping plate 6 away from the clamping member 7 is inclined. The end near the operating table 1 is greater than the height of the through groove 5, and the other end is less than the height of the through groove 5, so that the clamping member 7 is inserted between the clamping plates 6 and together inserted into the through groove 5. When the support plate 3 moves toward the center of the operating table 1, the clamping plate 6 clamps the clamping member 7 and inserts it into the through groove 5 to achieve fixation. Then, the position of the shell is fixed by the arc-shaped plate abutting against the outside of the metal shell.

[0033] Furthermore, the number of clamping members 7 is multiple, and the curvature and size of the arc plate are different, so different clamping members 7 can be selected for shells with different curvatures and sizes. The side wall of the clamping plate 6 that is in contact with the horizontal plate of the clamping member 7 is provided with anti-slip texture, so that the clamping member 7 is firmly fixed in the clamping plate 6.

[0034] Furthermore, the clamping component 7 and the clamping plate 6 are easy to assemble and disassemble. After the welding slag enters the gap, the clamping component and the clamping plate can be directly disassembled for cleaning. The welding slag is easy to clean and avoids positioning jamming.

[0035] Furthermore, the clamping component 7 has a water channel inside, and one end away from the center of the operating table 1 is connected to two circulating water pipes 8. The other end of the circulating water pipes 8 is connected to a chiller 9. The circulating water pipes 8 and the chiller 9 form a closed-loop cooling circuit. During the welding process, the chiller continuously delivers low-temperature coolant to the water channel of the clamping component, which quickly removes the heat conducted to the clamping component by the high-temperature welding, so that the clamping component is always maintained in a stable temperature range, avoiding dimensional changes or positional shifts due to thermal expansion and contraction, and ensuring firm and stable positioning.
